INTRODUCTION Multimedia Doman (MMD) specifications [3] enable an operator to apply Quality of Service (QoS) policy controls to the Internet Protocol (IP) Connectivity Access Network on session-based applications, and to provision flow-based charging rules at the Packet Data Serving Node (PDSN). These current specifications are confined to the PDSN as the sole policy enforcement point supported. The scope of MMD policy needs to be expanded to include overall coordination of network resource usage for Session Initiation Protocol (SIP) [4] and non-SIP applications for all subscribers, enhancements to policy contexts, and incorporation of additional network elements in the policy architecture. This document specifies the system requirements related to these MMD Policy Enhancements, which are intended to guide the associated technical specification development.
